I think that the review of Conquerclub is unfair, to be honest. I’ve played Risk on a few different sites, including Major Command, but I much prefer CC. The community have taken Risk and turned in into something more. You’ve got maps with bombardments, killer neutrals etc and you can play with many different settings like zombie or parachute spoils. As another reviewer mentioned, the classic map is very simple. It is based on the original Hasbro Risk board and is really not meant for more advanced players.
YES, the site is dated, and YES some of the others look more modern. But, many of the newer maps look pretty awesome and all have been made by the community. They still take map submissions from people who want to try something different. I don’t think that the look of the site takes away the enjoyment I get from the game as a player.
